How to deal with fault code p0299?

[LePreston]

Fault code p0299 is caused by the turbo or supercharger A being in a state of insufficient boost. To resolve this issue, you can repair the sticking of the supercharger bypass valve and its linkage mechanism, or address any blockages in the car's intake passage. Below is relevant information about automotive fault codes: 1. Fault code indicating excessively high fuel system concentration: When the pressure of the car's turbo or supercharger reaches the set maximum value, and components such as the wastegate, wastegate control valve, boost bypass valve, or boost pressure sensor malfunction, it can result in poor fuel efficiency, leading to a fault code indicating excessively high fuel system concentration. 2. Do not arbitrarily remove the battery's negative terminal cable: When a fault code appears and needs to be cleared, it must be done according to the method specified for the car's model. Under no circumstances should the fault code be cleared by arbitrarily removing the battery's negative terminal cable, as this may cause the car's central control computer to malfunction and could also result in certain features not working properly.
